[QUOTE="the Eel, post: 157677, member: 19952"] Al - you want to go to 30 on the pilot - is that why the bike hesitates down low ? 'Cause the pilot is too rich ? The reason I ask is because that is the only complaint I have - there is a hesitation when I roll on the throttle - not what I want when I'm trying to get over an obstacle on a 125 !!!! It also smokes quite a bit when I start it up. Is that another sign of the pilot being too rich ? The specs you mention - 390 main, 30 pilot - were exactly what was suggested to me by a Husky dealer in Michigan. However, there was a 2001 125 test in DirtRider executed at tracks local to me here in CA. DirtRider kept the 35 pilot (stock), went to a 410 or 400 main, and varied between 2 or 3 notches down on the clip (stock is 2 per the article). I changed the main to a 410 today and kept the pilot at 35. Unfortunately, since I've never fiddled with a carb before, I could not get to the needle. I couldn't get the darn throttle cable out of the slide housing !! Oh well. I also have a 390, a 400 and a 430 main. The 430 was in the bike when I bought it. It worked fine it seemed but I wanted to try something different to see what effect it had. I'm riding tomorrow - I'll report back on the results. Will changing the main affect the top end in any way ? It seems pretty flat on top. Also, is the choke off when it is all the way down ? Or all the way up ? I'm thinking all the way down is off. I hope that's right. I'll email you regarding the fax. Thanks ! [/QUOTE]
